Enraged mob farms.

Hey everyone!! Lately I have seen a lot of people talking about Enraged mob farms. I for one would love to have one of these, But everyone that has one is keeping them secret! So lets talk about it! I would like to talk about enraged mob farms and how to build them. I am also paying for access to an enraged mob farm! If you have a farm and you would like to sell access Pm me and I will get back to you ASAP

I have not seen them spawn in places they shouldn't, I've built with a fair amount of slabs before. I've learned recently that Iron Golems can't see slabs at all when they decide to spawn, thats only mob I know of that ignores them though.

I have a large(80x40x15) slabbed(and fairly well lit) area, and often get enraged mob spawns, granted it is in a cavern without roof over some parts, so it could be drop-ins, but I doubt the amount could be just that...

Could I just make a regular mob farm and use lava to kill the regular mobs but not the enraged? Then have a kill area and kill them myself for tokens and such? Come on people! I know there are people that have seen this and has a enraged farm. Lets hear about it!

The wiki says that enraged are just like normal mobs (same light level spawning), but MUCH rarer. I recently made a regular mob farm, but haven't got any enraged yet (of course, my mob farm is extremely inefficient). Lot of creepers though. I would try experimenting with a normal mob farm and making sure to light up other areas A LOT. Good luck! And if it works out well, I would love to see it so I can improve my mob farm.

I like to keep all my designs as it is very hard to make them and a lot of time and work goes into it so I don't want to just give it away. I also don't want the price to drop like the iron did with all the iron farms.

I wous start off seeing where they spawn then making different designs around the spawn. Mone is 200 200 blocks big.
